High-Density Concrete Blocks provide protection for a range of scenarios. They are made to site-specific spacial requirements for gamma and neutron radiation with five standard densities. In new construction or room upgrades, the interlocking design of our HD Block ensures shielding integrity. High-Density Concrete Blocks are an ideal solution for therapeutic modalities, including linear accelerators, proton therapy, and HDR rooms, as well as industrial applications requiring shielding materials. They can be utilized for maze walls and complete vault construction, with or without mortar (for modularity), depending on physics requirements and construction design. NELCO can even combine our High-Density Concrete Blocks with other materials for each unique shielding need.
